Values of ψ0,i are found in *NA to SS EN 1990: 2008+A1: 2010): Actionψ0
Imposed loads
Category A: domestic, residential areas : 0.7
Category B: office areas : 0.7
Category C: congregation areas : 0.7
Category D: shopping areas : 0.7
Category E: storage areas : 1.0
Category H: roofs : 0.7
*For MRT use Category C: congregation areas , ψ0 = 0.7
Wind loads on buildings : 0.5
Temperature : 0.6
Ed = γG∙Gk + γ∙Ad + ψ1∙Qk,1 + ψ2∙Qk,2
(near MRT Station : use Congregation area for ψ1 and ψ2 )
Leading variable : Imposed load (IL)
Ed = Self Weight + Strut Force + 1.0∙Ad + 0.7∙IL + 0∙Temperature
Leading variable : Temperature load (IL)
Ed = Self Weight + Strut Force + 1.0∙Ad + 0.5∙Temperature + 0.6∙IL
Note: Gk = Self Weight + Strut Force Ad = accidental load (such as impact or one strut removal) Qk,1= leading variable action (e.g., imposed load) Qk,2= accompany variable (e.g., temperature load)
